Fix issue #247 : Accepting non-integer parameters when shouldn't

Using `getLongFromObjectOrReply` instead of `atoi` if possible.
The following functions are modified.

* lrangeCommand
* ltrimCommand
* lremCommand
* lindexCommand
* lsetCommand
* zunionInterGenericCommand
* genericZrangebyscoreCommand
* sortCommand
